Ingredients
- 2 large sweet potatoes
- 1½ tablespoons olive oil
- 1 teaspoon cornstarch (optional but recommended for crispiness)
- ½ teaspoon salt
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika
- ¼ teaspoon black pepper
- Optional garnish: chopped parsley or grated parmesan
Instructions
- Prepare the sweet potatoes
Wash and peel the sweet potatoes if desired. Cut them into evenly sized fries about ¼ inch thick to ensure uniform cooking. - Soak for extra crispiness (optional but recommended)
Place the cut fries in cold water for 30 minutes to remove excess starch. Drain and pat completely dry with paper towels. - Season the fries
In a large bowl, toss the fries with olive oil until evenly coated. Sprinkle in cornstarch, salt, garlic powder, paprika, and black pepper. Toss again to distribute the seasoning. - Preheat the air fryer
Preheat your air fryer to 380°F (193°C) for about 3–5 minutes. Preheating helps create a crisp exterior immediately. - Cook in batches
Arrange the fries in a single layer in the air fryer basket. Avoid overcrowding to allow proper air circulation. - Air fry
Cook for 12–15 minutes, shaking the basket halfway through. Continue cooking until the fries are golden brown and crispy. - Adjust seasoning and serve
Taste and add additional salt if needed. Garnish with parsley or parmesan and serve immediately with your favorite dipping sauce.
The Secret to Crispy Sweet Potato Fries
Sweet potatoes contain more moisture and natural sugars than regular potatoes, which can make them softer when cooked. Here’s how to achieve crispiness:
- Dry thoroughly after soaking — moisture prevents browning
- Use cornstarch — creates a light crispy coating
- Avoid overcrowding — air circulation is key
- Cook at high temperature — encourages caramelization
- Serve immediately — they’re crispiest fresh from the fryer
